  4:   TAOBQNKLS - Bounded Quasi-Newton-Krylov Line Search method for nonlinear minimization with
  5:               bound constraints. This method approximates the Hessian-vector product using a
  6:               limited-memory quasi-Newton formula, and iteratively inverts the Hessian with a
  7:               Krylov solver. The quasi-Newton matrix and its settings can be accessed via the
  8:               prefix `-tao_bqnk_`. For options database, see `TAOBNK`

 10:   Level: beginner

 12:   Notes:
 13:   The base class for this method is `TAOBNK`

 15:   The various algorithmic factors can only be supplied via the options database
